[0002] As society's awareness of the importance of breastfeeding continues to increase, and modern women's demand for a balance between work and life continues to grow, the market demand for breast pumps as an auxiliary breastfeeding tool continues to expand. Existing breast pumps are designed in a variety of ways, aiming to provide breastfeeding women with a convenient and comfortable milk extraction experience while ensuring effective storage and hygienic safety of milk. Most early breast pumps were simple in structure and single in function. For example, manual pump breast pumps relied on users to manually squeeze the air bag or handle to generate negative pressure for milk extraction. Although the cost was low, the use process was cumbersome, and the efficiency and comfort were limited. With technological advances, electric breast pumps have gradually become the mainstream of the market. The electric motor drives the negative pressure pump to generate stable suction, which greatly improves the efficiency of milk extraction and user comfort.

[0003] With the advancement of technology, electric breast pumps have emerged. They generate stable suction through an electric-driven negative pressure pump, significantly improving the efficiency and comfort of breastfeeding, and are very popular among users. However, existing electric breast pumps still have certain limitations in terms of structural design, size and portability. Some products are complex in internal structure, large in size, and difficult to carry, which is not conducive to use by mothers who go out or work. Utility Model Content

[0027] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of a breast pump according to an embodiment of the present application.

[0028] In this embodiment, the breast pump may include: a milk bowl assembly 10, a main unit 20, a breast shield 30, and a diaphragm support 40. A milk storage space C is formed in the milk bowl assembly 10. A through hole T is formed in the main unit 20 in the thickness direction. The breast shield 30 has a narrow end and a wide end, and the narrow end of the breast shield 30 is passed through the through hole T. The main unit 20 is at least partially located between the wide end of the breast shield 30 and the milk bowl assembly 10. The diaphragm support 40 is connected to the milk bowl assembly 10 and extends into the milk storage space C.

[0029] In this embodiment, the milk bowl assembly 10 is used as a milk storage unit, and a special milk storage space C is provided inside the milk bowl assembly 10 for collecting and temporarily storing the milk sucked from the mother. The main unit 20 is provided with a through hole T that runs through the thickness direction thereof. The design of the through hole T not only helps to reduce the weight of the main unit 20 and save materials, but also provides space for the layout of other components, which helps to achieve miniaturization of the overall structure.

[0030] In this embodiment, the host 20 serves as the core power and control unit of the breast pump, and the host 20 integrates components such as a negative pressure pump, a control circuit, a battery, and a solenoid valve. The host 20 is provided with a through hole T that runs through the thickness direction thereof. The design of the through hole T not only helps to reduce the weight of the host 20 and save materials, but also provides space for the layout of other components, which helps to achieve miniaturization of the overall structure.

[0031] The wide end of the breast shield 30 is the part for contacting the user's breast. The breast shield 30 has a narrow end and a wide end. From the narrow end to the wide end, the narrow end is at least partially inserted into the through hole T of the main unit 20, thereby achieving a close fit with the main unit 20. At the same time, the main unit 20 is at least partially located between the wide end of the breast shield 30 and the milk bowl assembly 10. Such a layout helps to maintain the overall structural stability of the breast pump, and ensures effective connection and functional coordination between the main unit 20, the breast shield 30, and the milk bowl assembly 10 during the milking process.

[0032] The diaphragm support 40 is connected to the milk bowl assembly 10 and extends into the milk storage space C. A negative pressure chamber is formed in the diaphragm support, and the negative pressure chamber of the diaphragm support 40 is used to place the diaphragm 60, as described below.

[0033] In the embodiment of the present application, through the above-mentioned method, the thickness space occupied by the main unit 20, the milk bowl assembly 10, and the breast shield 30 as a whole can be reduced, and the diaphragm bracket 40 is connected to the milk bowl assembly 10 and extends to the milk storage space C inside the milk bowl assembly 10. The diaphragm bracket 40 does not occupy additional thickness space, further reducing the overall volume of the breast pump, making it convenient to carry.

[0034] In this embodiment, the breast pump may further include a milk suction duct 50 connected to the milk bowl assembly 10 and extending into the milk storage space C. The milk suction duct 50 is connected to the internal space of the breast shield 30, and the length of the milk suction duct extending into the milk storage space C is less than the length of the diaphragm bracket 40.

[0035] In this embodiment, the milk suction duct 50 is connected to the milk bowl assembly 10 and extends into the milk storage space C, and is communicated with the inner space of the breast shield 30. The milk suction duct 50 serves as a transmission channel for milk from the breast shield 30 to the milk storage space C, ensuring that milk can flow smoothly and efficiently from the breast into the milk storage space C of the milk bowl assembly 10 under the action of negative pressure, and avoiding leakage or blockage of milk during the transmission process. The milk suction duct 50 is communicated with the inner space of the breast shield 30, and the negative pressure generated during the milk suction process can directly act on the inside of the breast shield 30, prompting milk to flow into the milk storage space C through the milk suction duct 50. This design ensures the continuity and stability of the milk suction process. The length of the milk suction duct 50 extending into the milk storage space C is less than the length of the diaphragm bracket 40. This design helps to make the overall structure more compact, reduce the occupied space, and improve portability. The shorter milk suction duct 50 can reduce the possibility of milk residue in the duct, facilitate cleaning, and reduce the risk of bacterial growth.

[0036] Optionally, a milk outlet N is provided at one end of the milk suction duct 50 away from the breast shield 30, and the milk outlet N is used to flow the milk in the milk suction duct 50 into the milk storage space C. By arranging the milk outlet N at the end of the milk suction duct 50, it is convenient to clean the milk outlet N, and the position of the milk outlet N is more obvious, which is convenient for the user to observe the milk outflow, and the milk outflow situation can be effectively fed back to the user.

[0037] In one embodiment, the sum of the lengths of the milk suction duct 50 and the milk outlet N is less than or equal to the length of the diaphragm support 40. By setting the total length of the milk suction duct 50 and the milk outlet N not to exceed the length of the diaphragm support 40, it helps to maintain the compactness of the overall structure of the breast pump, especially for a portable breast pump, the size of the device can be reduced, and the convenience of carrying and using can be improved.

[0038] In one embodiment, the milk bowl assembly 10 includes a bowl body 11 and a cover plate 12, the bowl body 11 and the cover plate 12 enclose a milk storage space C, and the milk suction duct 50 and the diaphragm bracket 40 are both connected to the cover plate 12. The bowl body 11 can be set to be at least partially transparent, so that the user can observe the milk in the milk suction duct 50 through the milk bowl 11, or observe the milk flowing out of the milk outlet N, or it is convenient for the user to align the nipple position when wearing the breast pump. In some embodiments, a sealing ring can be set between the bowl body 11 and the cover plate 12 to ensure the sealing of the connection between the bowl body 11 and the cover plate 12, and prevent the milk in the milk outlet space C from overflowing.

[0039] In one embodiment, the milk suction duct 50 and the diaphragm support 40 are connected to the cover plate 12 as a whole. In some embodiments, the milk suction duct 50 can also be set to be detachably connected to the cover plate 12. Similarly, the milk suction duct 50 can also be set to be detachably connected to the cover plate 12.

[0040] In one embodiment, the milk suction duct 50 and the diaphragm support 40 are arranged side by side. By arranging the milk suction duct 50 and the diaphragm support 40 side by side, the thickness space occupied by the two can be further reduced, and the two share the thickness space, so that the breast pump can be thinner and lighter.

[0041] In one embodiment, the milk suction duct 50 is located above the diaphragm support 40. By arranging the milk suction duct 50 above the diaphragm support 40, the situation inside the milk suction duct 50 can be easily observed, and the milk suction duct 50 will not be blocked by the diaphragm support 40. The milk suction duct 50 is at least partially made of a light-transmissive material, so that the situation inside the milk suction duct 50 is easy to observe, such as the flow of milk and whether the nipple channel is aligned when the user wears it.

[0042] In one embodiment, the host 20 includes a transverse portion 21 and a longitudinal portion 22 bent and connected to the transverse portion 21, the through hole T is arranged on the longitudinal portion 22, the longitudinal portion 22 is located between the wide end of the breast shield 30 and the milk bowl assembly 10, the first side S1 of the milk bowl assembly 10 contacts the longitudinal portion 22 of the host 20, the second side S2 of the milk bowl assembly 10 contacts the transverse portion of the host 20, and the first side S1 and the second side S2 are two adjacent sides of the milk bowl assembly 10. In the above manner, an L-shaped step is formed on the host 20, and the milk bowl assembly 10 is arranged at the step of the host 20, which can facilitate the layout of the internal components of the host 20, and is more convenient for fixing the milk bowl assembly 10. The large contact area between the host 20 and the milk bowl assembly 10 can also facilitate the heat dissipation of the host 20.

[0043] In one embodiment, the breast pump further includes a diaphragm 60, which is used to be placed in the diaphragm support 40. The diaphragm 60 divides the internal space of the diaphragm support 40 into a first subspace and a second subspace. The first subspace is connected to the negative pressure interface of the host 20, and the second subspace is connected to the internal space of the milk suction duct 50. The diaphragm 60 can be driven by the negative pressure provided by the host 20 to deform in the internal space of the diaphragm support 40 to transfer the negative pressure to the milk suction duct 50, thereby generating the negative pressure required for milk suction in the milk suction duct 50. The diaphragm 60 is made of a flexible material and is mainly used to prevent the negative pressure from causing milk to flow back to the host 20 and causing damage to the host 20.

[0044] In one embodiment, the breast pump further includes a one-way valve 70, which is disposed at the milk outlet N. The one-way valve 70 is used to allow the milk in the milk suction duct 50 to flow unidirectionally into the milk storage space C. For example, the one-way valve may be a sheet-type one-way valve, or in other embodiments, a duckbill valve may be used. For example, when there is negative pressure in the milk suction duct 50, the one-way valve 70 is pressed against the milk outlet N under the action of suction, so that the milk in the milk storage space C cannot flow back. When the suction stops, the milk pushes the one-way valve 70 open under the action of gravity and flows into the milk storage space C.

[0045] The embodiment of the present application provides a breast pump including a milk bowl assembly, a main unit, and a breast shield. A milk storage space is formed in the milk bowl assembly, a through hole is formed in the main unit in a thickness direction, the breast shield has a narrow end and a wide end, the narrow end of the breast shield is penetrated by the through hole, the main unit is at least partially located between the wide end of the breast shield and the milk bowl assembly, the diaphragm bracket is connected to the milk bowl assembly and extends into the milk storage space, through the above manner, the thickness space occupied by the main unit, the milk bowl assembly, and the breast shield as a whole can be reduced, and the diaphragm bracket is connected to the milk bowl assembly and extends into the internal milk storage space of the milk bowl assembly, the diaphragm bracket does not occupy additional thickness space, further reducing the overall volume of the breast pump, and making it convenient to carry.
